Embodiment 1

[0023] The close-to-nature restoration of bird habitat was carried out in an abandoned sand mining field in the Baoquanling section of the Wutong River in Heilongjiang Province. The Wutonghe sand mining field has a history of more than 20 years, and some areas are currently abandoned, covering an area of ​​about 0.6 km 2 , ranging from 70 m to 90 m in width, and about 850 m in length. According to the historical investigation data and the field investigation results of the Wutong River habitat, the area is densely covered with marsh willow, elm, vitex, thick plum and other shrubs and trees on the shore before sand mining, and the bird habitat is highly suitable. A large number of songbirds, Climbers, raptors, swimmers and waders feed, rest or breed here. At present, the types of human disturbance in abandoned areas are mainly farmland and factory buildings. The main problems in bird habitats are: the landform types are sandy flats, deep water areas and sandbars, and there is ...

Abstract

The invention discloses a close-to-nature restoration method for a bird habitat in a waste sand yard in a cold region. The close-to-nature restoration method comprises the following implementation steps: 1) function division; 2) landform modification; 3) sand transformation; and 4) vegetation recovery. The method fully utilizes the bottom material and the geomorphologic characteristics of the waste yard, the close-to-nature restoration technique system of function division, landform modification, sand transformation and vegetation recovery is adopted, and the restoration of the service function of a river water ecosystem is promoted from the point of view of ecological integrity. The method reduces the ecological restoration difficulty of the sand yard, accelerates the restoration speed, is low in cost, has a good environmental benefit, and can be widely applied to the close-to-nature restoration of the bird habitat in the waste sand yard in the cold region, particularly the Songhua river basin.

Description

technical field [0001] The invention relates to a near-natural restoration method for bird habitats in abandoned sand fields in cold regions. Background technique [0002] Birds have high requirements for habitats, and changes in their community structure are often used to indicate habitat conditions. The key factors that determine the suitability of bird habitats are water, food and shelter, which are also key indicators that determine the health of river ecosystems. Therefore, evaluating the suitability of bird habitats can directly reflect the health of river ecosystems, and the near-natural restoration of bird habitats will also help to protect the health of river ecosystems. [0003] Frequent river sand mining has greatly damaged the physical and biological integrity of bird habitats in the Songhua River Basin, resulting in simplified habitat structures and low habitat suitability. At present, the protection of bird habitats in the Songhua River and its adjacent Heilo...
